Be it'known that 1,. FRANK PLUGER, a citi-zen ofthellmted Statesyand-a resident of Pf, itland,"county ofilultnomah; and

' cedar Wood,`fand nsince"tlhe'y receive a great' dealof'han'dling,m {bein-g shipped tofand tro,'I the 'klnocksto `u'fhich 'the bottom is' subjected has ate'ndenc'y`y to Vrender it loose and leaky; 'iyhiclrff course, 'tvas'tesfthe brine,

and 'may *u'ncfove'r t'lie 'cream l'container ftfo lFurtlie'rniore the lknoc'ls "Which the b'ottom 'ofL thei-staves of- `these`v4 rubsv vreceive tend to crush thelbettom ends'o'fthe-staves. It has been customary to 'affixa "false piece of harder Wood on the under side' ofthe bottom of the tub ;'but lthis did ln'ot providea complete remedy,-jbe'ca`u s e eedar'ivooddoes not hold nails \-.ell,-and`-so"the false piece became loose and no longer functioned properly.

esides the false piece did not function to prevent the bottom of the tub from becoming loose and leaky, which condition might arise because of the bottom of the tub drying out and shrinking.

The object of my invention is to provide a bottom for these Wooden tubs which Will make the bottom of the tub as a Whole so solid that it will remain in good condition indefinitely.

l attain my object in a Wooden tub comprising staves and a one piece bottom, the

latter having a flange at the top, which flange projects in a horizontal plane and is of Wedge shape in cross section; the bottom further having second flange parallel with and below the first mentioned flange; and preferably a third flange arranged like the second flange; said second and third flanges being of triangular cross section with the vertex of the triangle projection beyond the periphery of the bottom; the staves being provided on their interior .faces with a groove adapted toreceive said Wedge like top flange of the bottom piece. Thus, on the assembly Iand pressing of the staves of the-tub about the "bottom 'piece, t"the ltop flan-ge "of the .latter v`Will "Wedge in""saidl groove in the-"staves,andsaidsecond and third "ic-langes will be pressed into l theV sides of' the stzwes, and formiwithl the latter auxilliquid tight joints;l at'the` `sailnefti-me n contributing towards the rigidity of the bot# tom'of-tlietub asaavhole. My invention is illustrated/in panyir'ig` dranjzings,A in 'whichz Fig `l i'sayside' elevationl l ivrnprove'd tub Witha portion'brokeniavvay so astoshow the rv:above mentioned'-z details fof" the bottom'ottheftub;l I y 'i Figi 2 is atop'vieiv of myytub; Fig.v 3' is yasect-ional detailfillustratin'g "thel construction lof the bottom v4'View' Xyhidhis' slroivn in lexterior view and tliejeffect pro-z duced krwhen thel sta'ves are pressed "about tlie bottom piecc;`and i n Fig. 4l is a sectional detailfillustrating the" above mentioned "detail of 'constri'iction, the bottompicce being shown.y insection andas removed fronr the -staves and' ythe 'l face ofthe stares have indicated the're'inthe lign-'iid tight seats which will be formed Gnitsinterior faces with' said flan-ges of the bottom piece when the4 staves are 'pressed labout tle latter. It is to be noted in these drawings that the only seat prepared for my improved one piece bottom is a notch cut near the bottom of the tub. This notch f/ is slightly smaller in Width than the uppermost flange d of the tub bottom` Z). l/Vhen the sides of the tub a are compressed by means off the iron bands o, c and c2 this projecting Wedge d is forced into the notch g and the action of the Wedge like sides forces it Wider and make a Water tight joint. tion of the uppermost flange d the twotriangular flanges c and are formed in the tub bottom and are pressed into the stave sides of the container and thus make their own seat. This not only forms an added water tight seal but also makes the bucket more rigid and the natural racking is therefore much better taken care of. These triangular wedge flanges have no seats prepared for them but the only seats which they have are the indentations that they make upon the action of vcompression of the iron bands as before noted. Ashmy` improved tub bottom is made of only one piece of material and as it Willv seat in the staves at three separate places, all of which are a tight fit, it can be noted that big ad- Besides this acvantages are attained. The depression between the two triangular flanges in this tub bottom provides a space between the bottom b and the side walls a which can collect any seepage that might escape past the flanges d and e. This provides a reservoir in which the seepage water may be collected which would tend to swell this joint and therefore maintain the pressure between the bottom and the side-walls. depression the drying out of the bottom l) and the side walls would tend to relieve the pressure and thus cause the anges in my one piece bottom to become removed from their seats and thus permit leakage by the tub bottom until the water had.y swelled these parts again and restored this pressure. p

In the drawings the staves are connected to each other in conventional manner by means of the hoops c, c and c2 and at the top by means of wedges which tend to keep them from spreading apart because they are placed on the joints between the staves.`

It will be noted that the third flange is located near the base or bottom face of the tub and thus particularly functions to stiifen and support thebottom ends of the staves and prevent their being crushed in by the knocks which the tub receives.

Ivpreferably make my tub with a slight flare as shown in Fig. l and the staves are pressed about the bottom piece by means of the usual iron bands.

I claim:

1. A wooden tub comprising staves and a one-piece bottom, the latter being provided 'Without this with a peripherally projecting flange of wedge form in cross section, and being provided further with a second flange located below said first mentioned fiange, and with a third fiange located adjacent the under side of the bottom piece, said second flange being of triangular cross-section, the staves being provided on their interior faces with a -groove to receive said wedge like top flange of the bottom piece, whereby, on the assembly and pressing of the staves about its bottom piece said flange of triangular cross-section will be pressed into the opposed faces of the staves and form therewith a liquid tight joint, such joint also contributing to the rigidity of the bottom of the tub as a whole. j

2. A wooden tub comprising staves anda one-piece bottom, the latter being provided with a peripherally projecting flange of wedge form in cross-section, and being provided further with a second Harige located below said first mentioned ange, and with a third ange located adjacent the under side of the bottom piece, said second and third flanges being of triangular crosssection, the staves being provided on their interior faces with a groove to receive said wedge like top flanges of the bottom piece, whereby, on the assembly and pressing of the staves about its bottom piece said flanges of triangular cross section will be pressed into the opposed faces of the staves and form therewith a liquid tight joint, such joint also contributing to the rigidity of the bottom of the tub as a whole. f
